Letters Patent No. 90,905, dated June I, 1869.

The Schedule referred to in these Letters Patent and making part of theBama To all 'whom this may concern.:

v from the ame of the cultivator.

` Figure 3, a plan view of the rodwhich is used to raise and lower theshovels.

Figure 4, an elevation of one of the axle-tree arms, with the wheelremoved.

The present invention relates to an improvement in that class ofcultivators that run on wheels, and carry a frame that supports theworking-devices; and

Its nature consists in the novel means used to raise and lower theshovels, and give them aneasy lateral motion, and Ain supporting theforward ends of the beams with loop-bolts, so arranged as to give asidedraught, to counteract the pressure of the earth against themould-board shovels, when they are carried toward the row to form hillsand, further, in the novel means provided for so changing the positionof the beamsV from the front of the frame to a rear attachment, as toprovide a walking-cultivator, and so arranging the frame as to beadjustable on the axle-tree arms, for the purpose of balancing it, whenthe shovel-beams are changed, either into a walking or ridingoultivator.

To enable others skilled in the art to make and use my invention, I havemarked like parts, in the several figures, with like letters, and willnow give a detailed description.

A A, ig.1, represent a substantial frame, which is fastened together bycross-pieces E E, D D, and it is bolted fast to the axle-tree arms F F,at S S, two or more holes, T, being made through the frame, in front ofsaid arms, for the purpose of adjusting it far enough back to balance,when the operator is to walk in the rear ofthe cultivator, and guide theshovels.

The peculiar form of the arms is shown at g. 3, F'

v being the chair on which-the frame A bears, and a the back of thechair, which bears againstvthe inside of the frame, and prevents it fromgetting out of place.

To move the frame A back, all that is required is to remove the bolts SS from it, and put them through the holes T in front.

I do notV claim to have originated the principle` of balancing frames onaxles, to conform to walking and riding-cultivators, but limit myself tothe construction herein shown to accomplish this purpose.

The cross-pieces D E are fastened to the upper and lower side of the'ame A, by means of bolts K K, and they have a series of holes, I J,made through them, to receive'loop-bolts C O, which are putin either twoof the holes, J, (according to the width of the row to be cultivated,)when the operator is to ride, and in thev holes I, when he is to walk inthe rear, and guide the shovels L, by means of handles ff.

Each of the loop-bolts C has a long' shank, that is rounded at the upperend, and turns in the holes I, when the shovels L have alateral motion,and a pin ,put through its upper end, to hold it in place, a

washer, e, being put under the pin, to prevent it from g wearing. v

rIhe opposite ends of the bolts are so turned up as to provide suitableloops to support the forward ends of the beams B B, a series of holes, xx, Sto., being made through the loops, to receive the bolts which holdsaid beams in place.

It will be seen by this description, that the pivots U, ou which thebeams turn, are placed at the inner sides f the line of draught.

This is done that the shovels L may be easily thrown inward to hill arow, and held in that position with little or no force. v

The device for supporting and raising the shovels consists of an ironrod, G, figs. 2 and 4, which is `so bent at the ends as to form shortelbows mm and pivots W, and also a shank for securing the lever V, theelbows m operating as levers for raising the beams B B, and the pivots Wtting into sockets, or boxes, secured to the rear end of the frame A A.

The straight part ofthe rod supports sheave-block and pulleys H, theblocks supporting the chains, which are fastened to the beams B B, andused to raise and 'lower the shovels L, and the pulleys to roll on therod,

and thus permit the shovels to have au easy lateral motion, whether theyrun a greater or less depth in the ground.

A curved standard, N, fig. l, ls secured to the rear end of the tongueA, at U, and supports a latch, R,

which is pivoted to a short strap, P, fastened to said standard, and hasnotches in its under edge, which v lock over the rod G, and hold it inposition, the lever Y being used by the operator to put the rod inplace.

The operation is so simple as to require no particular explanation, thewhiletrees being attached to the draught-rods g g, and the operatorsitting on the seat r, when the beams B B are pivoted to the front ofthe cultivator, and walking in the rear, when they are pivoted to thecross pieces D D.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is l l. The rod G,in combination with the lever V,

sheave-blocks and pulleys H, beams B B, shovels L, 3. The combination ofthe frame A A, cross-pieces standard N, and catch R, the whole beingconstructed D E, loop-bolts C, beams B B, shovels L, and axleandarranged substantially as and for the purpose set tree arms F, said armsbeing adjustable on the frame, forth. and constructed as and for thepurpose described.

2. The combination of the loop-bolts C, beams B B, L. H. WILKINSON.shovels L, and cross-pieces D E, the latter having a Witnesses: seriesof holes through them, for adjusting the beams, R. W. TOVELL,substantially as herein described. M. RICE.
